Advocard [28]

A translocation that moves a gene from an area of euchromatin to heterochromatin would typically cause a(n) reduction in the expression of the gene.

<h3>What is euchromatin?</h3>
  • A kind of chromatin that is sparsely packed, enriched in genes, and frequently engaged in transcription is called euchromatin.
  • Contrasting with heterochromatin, which is compact and less accessible for transcription, is euchromatin.
  • The human genome has 92% euchromatic DNA.
<h3>What is heterochromatin?</h3>
  • Heterochromatin, often known as condensed DNA or densely packed DNA, has many different types.
  • Between constitutive heterochromatin and facultative heterochromatin, these variations fall on a spectrum. Both contribute to how genes are expressed.
  • Eukaryotic genomes contain heterochromatin, which serves a variety of purposes including regulating gene expression and preventing DNA replication and repair.
